So, it looks that we may get official press release already today, it's only matter of time. I read that Toto Wolf already confirmed news about Hamilton on Sky Sports News.
Very unexpected, we all thought it's going to boring off-season

. Hamilton to Ferrari, I didn't expected that one day I will see such thing. While Sainz is going to move to new Sauber/Audi project.
Yes the official announcement has finally arrived from Mercedes side.
They announced it on their official website: https://www.mercedesamgf1.com/news/mercedes-amg-f1-lewis-to-part-waysAt the end of the new season Lewis Hamilton is no longer going to be a Mercedes driver.

He joined Mercedes in 2013 you know. It has been a whole 11 years nearly... It would be a sad goodbye for Mercedes side I guess. Hamilton played a huge role in Mercedes to win constructor titles 8 times too. Who do you think Mercedes would replace Hamilton with? Maybe Mick Scumacher or someone else?
